As we treat it as a name we should capitilize each word, but we forgot

Use the correct register (Yn_01) with first half of the
Y samples instead of using the register (Yn_23) with the
second half twice when computing the green channel.
Also use the Yn_01 register name instead of Yn for the red
channel as well, just for a bit of extra consistency.

Currently we add fake modes to cater for applications that want to
change the screen size but limit themselves to only those that are
available, and do not wish to either use RandR scaling or their own. For
widescreen panels, these 4:3 aspect ratio modes require panel fitting
and so are less than satisfory. Since we add fake modes, let's add a few
common widescreen modes as well (choosing the right aspect ration for
the panel).

Sometimes we want to render with the GPU when doing a mode switch, e.g.
if we need to initialise an output surface. To do so, we need to prepare
the acceleration layer first.
Lots of thanks to Vasily for tracking this one down.

An oversight when enabling efficient sharing of the shadow_crtc (i.e.

When using Xinerama, RandR is automatically disabled, and calling RR
routines will trigger an assert() because the RR keys/resources are
not set, leading to an Xserver abort.
Hotplug makes little sense without RandR, so no need to install a
udev monitor if RandR is not available, as done in sna.

Make sure we clear the scanout even after the error paths before
attaching the shadow buffer (in case it is full of unwanted junk).

In cases of stress, we use a timer to create a fake vblank event and
then we adjust the timer when it fires to match it up with the CRTC msc.
However, sometimes we fire before the vblank but less than a millisecond
and so below the precision of the timer causing us to send notifies too
early. Use a blocking vblank wait to fixup these rare cases.

Otherwise we may process a SIGIO moving the cursor away from the CRTC
causing us to remove the cursor and then process a stale pointer inside
the modeset after the signal is complete.

During swapbuffers, the sw cursor tries to write to the old buffer.
Ordinary this is not an issue as we are discarding it, but under
TearFree that write causes us to instantiate the shadow buffer with a

sna/dri2: Prevent the sw cursor from copyig to a buffer as we discard it
Tried to fix it by disabling SourceValidate. However, it a direct hook
into the Damage code by miSprite that triggers the copy. Since there
appears to be no way to intervene, we just mark that copy as internal
and ignore it.

Normally hard coding pkg-config is considered a bad idea. Please

We were not updating the window->crtc for the immediate swaps with the
result that after switching CRTCs, we were requesting a vblank on the
wrong pipe and triggering an error path (forcing the blit and negating
the elision).

We expect mesa nowadays to preferentially use the render pipeline for
